A Lancaster physicist has proposed a radical solution to the question of how a charged particle, such as an electron, responded to its own electromagnetic field.

This question has challenged physicists for over 100 years but mathematical physicist Dr. Jonathan Gratus has suggested an alternative approach—published in the Journal of Physics A: Mathematical and Theoretical with controversial implications.

It is well established that if a point charge accelerates it produces electromagnetic radiation. This radiation has both energy and momentum, which must come from somewhere. It is usually assumed that they come from the energy and momentum of the charged particle, damping the motion.

It could hardly be more complicated: tiny particles whir around wildly with extremely high energy, countless interactions occur in the tangled mess of quantum particles, and this results in a state of matter known as “quark-gluon plasma”. Immediately after the Big Bang, the entire universe was in this state; today it is produced by high-energy atomic nucleus collisions, for example at CERN.

Such processes can only be studied using high-performance computers and highly complex computer simulations whose results are difficult to evaluate. Therefore, using artificial intelligence or machine learning for this purpose seems like an obvious idea. Ordinary machine-learning algorithms, however, are not suitable for this task. The mathematical properties of particle physics require a very special structure of neural networks. At TU Wien (Vienna), it has now been shown how neural networks can be successfully used for these challenging tasks in particle physics.

By using hypernetworks, researchers can now preemptively fine-tune artificial neural networks, saving some of the time and expense of training.

SpaceX launched a Falcon 9 rocket back in 2015, and its second stage is on course to hit the Moon. The DSCOVR craft stage could send up lunar regolith.

A new biosensor chip can observe direct electrical measurements of single-molecule interactions. This could enable faster and cheaper DNA sequencing, disease surveillance, and precision medicine on portable devices.

Annually for three years, The Lemelson Foundation will give $100 awards to outstanding inventors in up to 270 Society Affiliate Fairs with middle school participants around the country. The prize was specially created to reward young people whose projects exemplify the ideals of inventive thinking by identifying a challenge in their community and creating solutions that will improve lives.

Invasive algae are often found in bodies of water such as lakes and ponds, but can it be used as paper? Seventh-graders, Wyatt Vick and Charley Clyne, from Zane Trace Middle School in Chillicothe, Ohio, set out to answer that question with their project, “Algae Paper,” eventually earning them the Lemelson Early Inventor Prize.

Roughly 13.8 billion years ago, our Universe was born in a massive explosion that gave rise to the first subatomic particles and the laws of physics as we know them. About 370,000 years later, hydrogen had formed, the building block of stars, which fuse hydrogen and helium in their interiors to create all the heavier elements. While hydrogen remains the most pervasive element in the Universe, it can be difficult to detect individual clouds of hydrogen gas in the interstellar medium (ISM).

This makes it difficult to research the early phases of star formation, which would offer clues about the evolution of galaxies and the cosmos. An international team led by astronomers from the Max Planck Institute of Astronomy (MPIA) recently noticed a massive filament of atomic hydrogen gas in our galaxy. This structure, named “Maggie,” is located about 55,000 light-years away (on the other side of the Milky Way) and is one of the longest structures ever observed in our galaxy.

A new Commerce Department report highlighted the severity of a global shortage that has hobbled manufacturing and fueled inflation for more than a year, and that defies easy solutions.

Tesla appears to have finally agreed to walk back one feature of its controversial yoke steering wheel, as it will now provide a regular horn.

When Tesla unveiled the new Model S with the “yoke” butterfly steering wheel, it was controversial. Some were worried about the actual shape of the wheel being problematic, while others were concerned about the lack of drive stalk to choose the drive mode.

As for the former, we thought that the automaker wouldn’t risk bringing the controversial yoke steering wheel to market without a nonlinear steering curve enabled by a steer-by-wire system – especially knowing that Tesla has been developing a steer-by-wire system.
